May 13, To prevent any confusion with the eGo-type " batteries ", I use the term "cell" here to refer to a single,etc. While the test results are hard data, the conclusions and recommendations I make based on these tests are only my personal opinion based on my criteria for setting a rating.

Carefully research any cell you are considering using before purchasing. Testing cells at their limits is dangerous and should never, ever, be attempted by anyone who has not thoroughly studied the dangers involved and how to minimize them. If the cell has only one current rating number on it, or if it says "max discharging current" then I have to assume that the company is stating that the cell can be discharged at that current level in any way, including continuously. This A is a true high performance cell that I am rating at a cool-running 30A mAh.

It performed well against the top cells for performance, vaping time, and safety high amp rating. The A While this cell will only fit in a custom battery sled it did just fit in the Xtar and Efest chargers I tested it in.

I cannot say if it will fit in any charger. Otherwise it's charged at 4. It's "standard" charging rate is 2.

Thank you! This is good performance for a mAh cell at 10A so I am rating it at mAh. This is just below the average temperature for a cell being discharged at its continuous discharge rating CDR but the datasheet seems to show a higher sensitivity to temperature than our 's so I am not giving it a rating above 30A. I am setting a CDR of 30A for this cell. While operating any cell near its rated maximum current level causes damage, I would expect decent cycle life at 30A continuous.

Custom crafted ceramic holders maybe? There is definitely being generated a lot of heat, but I do not really know if it is the holder or the battery. The inner pin do not generate any heat, the current is virtually zero. The battery gets hot and probably faster than my thermo sensor can follow.

The contact surface between battery and holder may also generate heat, just 1 milliohm would be 2. The wire connection at the back may generate some heat. The cable is getting warm, I uses 2.This product is eligible for further discounts depending on how many you buy!
